Modeling the ferroelectric phase transition in barium titanate with DFT accur...
The accurate description of the structural and thermodynamic properties of ferroelectrics has been one of the most remarkable achievements of Density Functional Theory (DFT).... -
Orbital-resolved DFT+U for molecules and solids
We present an orbital-resolved extension of the Hubbard U correction to density-functional theory (DFT). Compared to the conventional shell-averaged approach, the prediction of... -
Phonon-limited mobility for electrons and holes in highly-strained silicon
Strain engineering is a widely used technique for enhancing the mobility of charge carriers in semiconductors, but its effect is not fully understood. In this work, we perform... -
Jahn-Teller effect in the cubic fullerides A₃C₆₀
Compared to isolated C₆₀³⁻ ions, characterized by a three-dimensional equipotential trough at the bottom of the lowest adiabatic potential energy surface (APES), the Jahn-Teller... -

The initial stages of cement hydration at the molecular level
Cement hydration is crucial for the strength development of cement-based materials; however, the mechanism that underlies this complex reaction remains poorly understood at the... -
Spectroscopic investigations of complex electronic interactions by elemental ...
Doping and compositing are two universal design strategies used to engineer the electronic state of a material and mitigate its disadvantages. These two strategies have been... -
Automated all-functionals infrared and Raman spectra
Infrared and Raman spectroscopies are ubiquitous techniques employed in many experimental laboratories, thanks to their fast and non-destructive nature able to capture... -
Nonempirical semilocal density functionals for correcting the self-interactio...
Through the use of the piecewise-linearity condition of the total energy, we correct the self-interaction for the study of polarons by constructing nonempirical functionals at... -
Self-interaction and transport of solvated electrons in molten salts
The dynamics of (few) electrons dissolved in an ionic fluid—as when a small amount of metal is added to a solution while upholding its electronic insulation—manifests... -
Hydrodynamic finite-size scaling of the thermal conductivity in glasses
In the past few years, the theory of thermal transport in amorphous solids has been substantially extended beyond the Allen-Feldman model. The resulting formulation, based on... -

Dynamics of the charge transfer to solvent process in aqueous iodide
Charge-transfer-to-solvent states in aqueous halides are ideal systems for studying the electron-transfer dynamics to the solvent involving a complex interplay between... -
Complexity of many-body interactions in transition metals via machine-learned...
This work examines challenges associated with the accuracy of machine-learned force fields (MLFFs) for bulk solid and liquid phases of d-block elements. In exhaustive detail, we... -
On the sign of the linear magnetoelectric coefficient in Cr₂O₃
We establish the sign of the linear magnetoelectric (ME) coefficient, α, in chromia, Cr₂O₃. Cr₂O₃ is the prototypical linear ME material, in which an electric (magnetic) field... -
Non-equilibrium nature of fracture determines the crack path
A high-fidelity neural network-based force field (NN-F³) is developed to cover the space of strain states up to material failure and the non-equilibrium, intermediate nature of... -
